TOPA dominates DC investor conversations — but DOPA (District Opportunity to Purchase Act) is the statute that kills 5+ unit affordable acquisitions when sponsors treat them like suburban garden apartments. When 25% or more of units in a 5+ rental unit housing accommodation qualify as affordable, the District holds a subordinate purchase right after tenants pass on TOPA — and DHCD can assign that right to a qualified developer who must preserve and expand affordable units.
This guide is for small multifamily buyers, value-add bridge sponsors, and 1031 exchangers targeting DC buildings with HAP contracts, LIHTC adjacency, or legacy affordable covenants — not institutional LIHTC syndicators. Pair with TOPA compliance, RENTAL Act reform, and 1031 bridge timing.
Official reference: DHCD — District Opportunity to Purchase Act (DOPA)
When DOPA triggers — investor screening
| Criterion | Threshold |
|---|---|
| Unit count | 5+ rental units in the housing accommodation |
| Affordable share | 25%+ of units meet statutory affordable definition |
| Sale event | Bona fide offer of sale or transfer meeting DOPA notice rules |
| TOPA sequence | District right is subordinate — tenants get first clock |
Section 8 units are not automatically exempt from affordable classification — verify HAP and rent restrictions on the rent roll.
Not DOPA: Most 2–4 unit rowhouses — those run through TOPA/RENTAL Act instead. Two-four unit vs SFR guide · DSCR multi-family DC

Investor takeaway: Underwrite TOPA days + DOPA days + lender seasoning — not purchase agreement date alone.
Who uses DOPA — and why it blocks private buyers
DHCD uses DOPA to:
- Preserve affordable units at risk of market-rate conversion
- Address problem properties when tenants cannot execute TOPA
- Assign purchase rights to pre-qualified developers via RFQ pool (DHCD DOPA page)
Private investors competing on market-rate repositioning lose when the District exercises or assigns rights — your hard money balloon and 1031 deadline do not pause for DHCD process.
Diligence checklist — before LOI on 5+ unit DC
- Unit count and affordable percentage — rent roll + HAP contracts + DHCD registrations
- Recorded affordability covenants — title commitment schedule B
- TOPA status — occupied vs exempt building class under RENTAL Act
- DOPA notice history — prior failed sales may leave open filings
- Counsel letter — DOPA/TOPA clearance opinion for lender file
- Bridge term — 12-month minimum if any notice period unresolved
- 1031 coordination — map DOPA clock inside 45/180-day window — DMV 1031 guide
Worked example — 8-unit Brookland value-add
Profile: 1920s apartment building, 8 units, 3 Section 8 / HAP, 2 rent-controlled below market, 3 market.
| Factor | Analysis |
|---|---|
| Affordable share | 5/8 = 62.5% — DOPA likely applies |
| Acquire basis | $1.45M ($181K/door) — looks cheap |
| Rehab budget | $320K |
| Hard money | 75% LTC bridge @ 11% IO |
| Hidden risk | Seller never filed DOPA clearance on prior failed sale |
| Legal + holding | 4-month TOPA/DOPA stack = ~$53K IO + $25K counsel |
| Outcome | District assigns to affordable developer — deposit lost, bridge payoff from equity |
Alternative: Brookland hard money on 4-unit exempt row — higher basis per door, no DOPA.
Financing products — how lenders treat DOPA
| Product | DOPA sensitivity |
|---|---|
| Hard money / bridge | High — needs counsel clearance letter |
| DSCR 5+ unit | High — stabilized affordable mix affects rent growth |
| Commercial lending DC | Medium — sponsor experience with DHCD process |
| 1031 exchange bridge | Critical — calendar risk |
Lenders price uncertainty in points and term — not just LTV.
Strategies that survive DOPA scrutiny
| Strategy | Fit |
|---|---|
| Market-rate 5+ new construction | Often exempt paths — verify CO date under RENTAL Act |
| 4-unit rowhouse stack | Avoid DOPA entirely — watch TOPA reform |
| Fee-simple affordable preservation | Institutional — not typical hard money |
| DMV suburb 5+ | Prince George’s DSCR — no DOPA |
When to walk away
- Seller cannot produce affordable unit registry or HAP contracts
- 62.5%+ subsidized rent roll with market-rate business plan
- 1031 replacement with under 90 days left and no DOPA pre-clearance
- 6-month hard money term on occupied 8+ unit affordable stock
LIHTC and HAP — how affordable share gets counted
| Income type | DOPA relevance | Diligence doc |
|---|---|---|
| Project-based Section 8 | Counts toward affordable share | HAP contract + DHCD registration |
| Tenant-based voucher | May not count as building-affordable | Tenant files, not building covenant |
| LIHTC restricted units | Often counts — repositioning triggers notice | LURA / regulatory agreement |
| Rent-controlled below market | Not automatically “affordable” for DOPA | Statutory definition — counsel |
A market-rate sponsor buying LIHTC-adjacent stock without reading the LURA is how $50K earnest money dies in DHCD review. Institutional sellers know the clock; private estate sellers often do not.
TOPA reform interaction (2026)
RENTAL Act changes TOPA exemptions on newer construction and some 2–4 unit transfers — but 5+ unit affordable buildings remain the highest-friction sale class. Even when TOPA offer-of-sale is shortened, DOPA notice may still run. Read RENTAL Act reform alongside this guide — not instead of it.
Worked timeline — 12-unit Columbia Heights (illustrative)
| Day | Event |
|---|---|
| 0 | PSA signed — $1.62M, 40% affordable per seller rep |
| 14 | TOPA offer of sale delivered to tenants |
| 60 | Tenant organization declines purchase |
| 65 | DOPA notice filed with DHCD |
| 120 | District elects to assign purchase to qualified developer |
| 125 | Private buyer released — or deal dies |
Bridge cost: $1.62M @ 11% for 120 days ≈ $59K IO + $30K legal — must be in pro forma before LOI, not after DOPA surprise.

DOPA — multifamily acquisition gates (2026)
- Rent roll audit: count affordable units under statutory definition, not broker labels
- 1031: map DHCD response window inside 180-day replacement period
- Bridge term: 12-month minimum on occupied 5+ with 25%+ affordable
- Counsel letter: required for most commercial and multifamily DSCR desks
- Earnest money: keep refundable until DOPA clearance or price the risk in the deposit structure
TOPA vs DOPA vs neither — decision matrix
| Building profile | TOPA | DOPA | Typical private buyer |
|---|---|---|---|
| 2–4 unit row, market rent | Notice / reform path | No | Flip / BRRRR sponsor |
| 5+ unit, under 25% affordable | Yes | No | Small multifamily |
| 5+ unit, 25%+ affordable | Yes | Yes | Institutional / DHCD assignee |
| New construction (exempt CO date) | Reduced | Maybe | Merchant builder |
| LIHTC / HAP heavy | Yes | High | Preservation specialist |
1031 exchange — worked calendar risk
Profile: Exchangor sells Virginia rental, identifies 8-unit DC Brookland replacement ($1.55M, 50% affordable).
| Day | Event | 1031 risk |
|---|---|---|
| 0 | Relinquished property closes | 45-day ID period starts |
| 20 | Replacement identified | OK |
| 45 | TOPA offer of sale on replacement | Clock running |
| 90 | DOPA notice filed — District reviewing | 180-day window burning |
| 150 | District assigns to affordable developer | Exchange fails — taxable gain |
Bridge fix: 1031 exchange bridge on replacement only after counsel letter confirms DOPA clearance — or choose 4-unit DC / PG County replacement without DOPA.
Questions for seller — before LOI on 5+ units
- “What percentage of units are affordable under DHCD definition?”
- “Are there HAP contracts or LIHTC restrictions on title?”
- “Has a prior sale triggered DOPA notice? Outcome?”
- “Any TOPA assignment history from tenant organizations?”
- “Will seller deliver DHCD correspondence on DOPA status?”
If seller answers “I don’t know” on affordable share, treat as DOPA applies until counsel proves otherwise.
Estate and distressed sales — hidden affordable mix
Heirs selling 1920s apartment buildings often mislabel units as market when long-term tenants pay below FMR with informal HAP or rent-control status. Probate sale “as-is” does not waive DOPA. Budget rent roll audit ($2K–$5K) before earnest money on any 6+ unit inheritance.
Bridge lender term sheet — DOPA items
| Term sheet ask | Why |
|---|---|
| 12-month initial term | TOPA + DOPA stack |
| Extension option 6+ months | DHCD delay |
| Interest reserve 4–6 months | Occupied hold during notice |
| Counsel opinion as funding condition | DOPA clearance |
| Lower LTV (65–70%) | Exit uncertainty |
Bridge loans Washington DC desks price regulatory tail risk in points — not just LTV.
Market-rate repositioning — when DOPA blocks the thesis
Sponsors buying 62.5% affordable buildings to convert market-rate after rehab face dual blockers:
- DOPA on sale (if you sell)
- Rent control / HAP on turnover (if you hold)
- BEPS on 5+ unit systems capex — BEPS guide
The value-add spread that works in Prince George’s County often does not exist in DOPA-covered DC stock at the same basis.
DOPA clearance documentation — file for lender
Build a closing binder with:
- Tenant TOPA waiver or expiration letter
- DHCD DOPA response or no-interest letter
- Rent roll with affordable unit schedule
- Title commitment without unreleased affordability covenants
- Counsel opinion letter
Missing one item delays commercial or multifamily DSCR funding — even when purchase price is attractive.
